photographic (adj.)

"a picture obtained by any process of photography," 1839, coined by English polymath and photography pioneer Sir John Herschel (son of the astronomer) from photo- "light" + -graph "something written."

It won out over other suggestions, such as photogene and heliograph. Photogram (1859), based on telegram, did not catch on. Neo-Anglo-Saxonists prefer sunprint; and sun-picture (1846) was an early Englishing of the word. The verb is first found (along with photography and photographic) in a paper Herschel read before the Royal Society on March 14, 1839. Related: Photographed; photographing.

Middle English -ik, -ick, word-forming element making adjectives, "having to do with, having the nature of, being, made of, caused by, similar to," from French -ique and directly from Latin -icus or from cognate Greek -ikos "in the manner of; pertaining to." From PIE adjective suffix *-(i)ko, which also yielded Slavic -isku, adjectival suffix indicating origin, the source of the -sky (Russian -skii) in many surnames. In chemistry, indicating a higher valence than names in -ous (first in benzoic, 1791).

In Middle English and after often spelled -ick, -ike, -ique. Variant forms in -ick (critick, ethick) were common in early Modern English and survived in English dictionaries into early 19c. This spelling was supported by Johnson but opposed by Webster, who prevailed.
